208 COMPARISON OF THE NATURAL ORDERS 



section of the 12th Order, Holeracece. Jussieu has 

 them all amongst his Amaranthi 30, except Phyto- 

 lacca, which is one of the Atriplices 29. 



£ Nymphcea and Sarracenia are both transferred 

 to the 27th Order, with a query whether the latter 

 especially may not be akin to Asarum, and therefore 

 to the Sarmentaceee, Ord. 11. We find that Linnaeus 

 once placed both these genera, as well as Aristolochia, 

 and it's allies Asarum and Cytinus, in his 1 1th Order. 

 He had a fanciful idea of an affinity between Nym- 

 phcea and Sarracenia, founded on the singular eco- 

 nomy of the leaves in the latter. These he supposed 

 to be contrived for the purpose of affording the plant 

 a continual supply of water, which, like it's aquatic 

 relation, it might require. Jussieu but faintly hints 

 at the affinity in question, placing Sarracenia among 

 the plant a incertce sedis. 



71 Cedrela and Swietenia are both removed to the 

 23d Order, along with Turrcea Linn. Mant. 150. 

 They all undoubtedly belong to the 1st section of 

 that Order, being among the Melice, 71, of Juss. 



^ Telephium, Limeum and Corrigiola are trans- 

 ferred to the 5th section of the Holeracece, Ord. 12. 

 Jussieu has them all in his Portulaccct 86, on account 

 of their being furnished with petals ; which circum- 

 stance here, as in the instance of his 82d Order com- 

 pared with the 30th, breaks the natural chain of his 

 system.
